Mistake rib stitch
Mistake rib stitch looks complex but is surprisingly easy. It forms ridges that almost look like a furrowed field, recently ploughed! Mistake rib stitch doesn't behave like other rib stitches. It doesn't gather the fabric in but gives you nicely textured, thick and warm knitting.
